Abstract
An apparatus for dispensing a carbonated beverage includes a sub-chamber () that communicates with a main container (). In use, prior to filling the sub-chamber () it is pressurised to greater than or equal to the equilibrium pressure required to keep the dissolved gas in solution. This has the effect that the beverage does not froth out of a dispenser nozzle. It also has the effect of keeping beverage in the main container () from losing carbonation. The invention has particular application to 'Optic' devices for dispensing carbonated spirit drinks.
